“Which is now, whether we like it or not, is the biggest threat multiplier we face because what is happening now is what I was dreading.

“Which is we are having to deal all the time with the symptoms that are springing up all round the world, and they are diverting us off down all these different channels to try and deal with ghastly conflicts and humanitarian and natural disasters, and goodness knows what else.

“At the root of it all, much of it, is climate change which is causing untold horrors in different parts of the world.”

During their discussion, Charles agreed with Harry that a number of options do already exist in terms of addressing climate change when it comes to the younger generation and technology.

HRH The Prince of Wales said: "We have somehow abandoned our proper connection with nature. Somehow imagined that we can manage without or we battle against her in every way instead of understanding that the future lies in working in far greater harmony with nature."

As Harry added “our mindsets”, Charles said this is where he thinks it has gone wrong in that we “have somehow abandoned our proper connection with nature”.

He said it is like we have “somehow imagined we can manage without or we battle against her in every way”.

“Instead of understanding that the future lies in working in far greater harmony with nature and trying to ensure more successfully that our own economy better mimics and mirrors nature’s brilliant economy,” he added.

After Harry chipped in with “a circular economy as opposed to a linear economy”, responding to that, Charles said the concept of a circular economy is one which quite a lot of people have been working on.

He added that a “circular economy is much more one which mimics nature’s remarkable capacity to never waste anything”.
